Fujitsu R407c conversion. Help.

[PcT]

Can anyone advise what type of synthetic oil to use in the compressor for a Fujitsu AOY18RZCL split system that has been converted rrom R22 to R407c? There's just too many to choose from and I can't find anyone who with a sensible answer.

Thanx

That is Tecumseh compressor, probably piston type.

It is important that right viscosity is used.

These are Tecumseh approved oils, but you need to find out viscosity for your case.
Send them (at "contact us" tab) question with compressor model no. and I am sure that you will get right information.
